Exeter's unique medieval water system

Water in the City: The Aqueducts and Underground Passages of Exeter by Mark Stoyle, a new book published by the University of Exeter Press, looks at the complex water supply system, dating to the 14th century, that once served the medieval city and now still exists beneath its streets.

The city's system includes a labyrinth of stone-lined, vaulted tunnels which held pipes that carried the water. This network required much maintenance. Author Mark Stoyle writes, "People from all social backgrounds relied on the system to provide their drinking water, so it was vital to keep it running smoothly. The city retained a plumber to carry out regular maintenance and he, in turn, hired in a team of workers to help with specific jobs."
